Abstract
A display device including color filters overlapping each other on a non-emitting area of an upper substrate which is opposite to a lower substrate is provided. In the display device, color filters disposed close to a white emitting area include a same material, and the color filters extend a greater distance onto a non-emitting area disposed near the white emitting area, relative to distances extended onto other non-emitting areas. Thus, the display device may prevent light-leakage from the white emitting area.
